Monoecious; staminate inflorescences catkin-like; pistillate inflorescences catkin-like. Flowers inconspicuous; bracts imbricate, triangular, 2–3 × 1–1.5 cm, margins double-serrate.

The best-known specimens of this hybrid in cultivation are at the Sir Harold Hillier Gardens, two of which were grown from seed collected by Roy Lancaster and Ann Ala (Lancaster & Ala 5) in 1972, now fine vigorous trees of 9–10 m. The habit is described as ‘upright’ by Hillier & Coombes (2002). Carpinu ×schuschaensis is available in the nursery trade in continental Europe, the United Kingdom and the United States.
